Patented Get. 9, 1951 UNITED. STATES-PATENT OFFICE Q I "2,570,936 YREMOVABLE vvrNDow SASH Roy J. .Riley; 'lulsa, Okla. Application Aug ust23, 1945, Serial No. e azzs' 3 Claims. (01.20%1) The invention relatesto removable window the sash can be inwardly moved from the window frameor hinged inwardly at their lower ends.

A furtherobje'ct is to interpose a metallic strip between the sides ofthe sash and the frame and to provide the strip with a vertical channelfor the reception of the spring roll of the parting strip and the inneredge of the plate or metallic strip with an inturned roll for thereception of the roll of the inside strip which is sprung intoengagement with a spring moulding carried by the inside sash.

A further object is to make the upper sash narrower than the lower sashso that the parting strip, when hinged inwardly, will allow the uppersash to clear the strip. I

A further object is to so shape the parting strip roll and channel ofthe metallic spring carried strip that the parting strip will closelyhug the metallic strip when in inoperative'position.

A further object is to provide a spring strip between the sash andparting strip and acting against the hinged inside strip.

With the above and other objects in view the invention resides in thecombination and arrangement of parts as hereinafter set forth, shown inthe drawings, described and claimed,

it being understood that changes in the precise embodiment of theinvention may be made within the scope of what is claimed withoutdeparting from the spirit of the invention.

' In the drawings: 1 Figure 1 is a detail perspective view showing insection the side of a window frame, the sash andthe various strips.

Figure 2 is a horizontal sectional view through the inner side of thewindow frame, 'a portion of the lower sash and the inside strip.

Figure 3 is a horizontal sectional view through a portion of the frameand upper sash, showing the parting strip in open position for removalof the upper sash.

Figure 4 is a horizontal sectional view through a window frame showing amodified form of inside strip.

Figure 5 is a view similar to Figure 4 showing a further modified insidestrip.

Figure 6' is a, perspective view of the form shown in Figure 4. 5

Figure 7 is a vertical transverse sectional view through the windowframe and sash, showing the sash tilted inwardly. I Figure 3-isa'p'erspectiveview of the sashlift used' as a hinging point for the lower sashas shown in Figure "'7.

Figure 9 is a vertical view showing a, modified form ofstrip; v Figure10 is a perspective view of thestrip shown in Figure 9.

Figure 11 is an enlarged detail of Figure 9. Figure 12 is a modifiedform of strip mounting. Referring to the drawings, the numeral 1designates the side of a conventional form of window frame from whichthe usual inside strip and parting strip are removed. 'Secured tothe-frame I are'filler strips 2 and 3. The filler strip 2 is narrowerthan the filler strip 3 and registers with-the side of the lower sash 4while the filler strip 3 registers with the side of the upper sash 5.These strips are of different width so that the upper sash 5 will'hinge'inwardly as shown in Figure '7, thereby clearing the hinged partingstrips 6 as shown in Figure 3. The side of the frame I is provided witha vertically extending facing strip I, extending around or over fillerstrips 2 and 3, and providedwith a rectangularly shaped channel 8 forthe reception of the spring roll 9 of the parting strip 6. The springroll allows the parting strip 6 to flex and to snap to operative or'inoperative position, shown in dotted lines in Figure 3. Parting strip 6is bent upon itself at H] and is received in the channel H of the facingstrip 1 when in open position. The outer edge of the facing strip 'lterminates in a spring flange I2- in the groove I3 in the outer face ofthe upper sash 5 thereby forming a guide and a weather stripping.

The inner edge of the facing strip 1 is provided with a verticallydisposed roll M, in which is disposed and hingedly mounted the roll I5ofthe flexible inside strip l6, which inside strip springs into thechannel I! of the spring moulding l8 carried by the inner face of thelower sash 4. The strip I6 is forced to the full line position shown inFigure 2 when it is desired to remove the lower sash, and at which timethe lower sash has been moved to its lower position, as shown in Figure7, so that the screw head I9 is received in the enlarged end 20 of thearcuate slot 2! in the sash lift, and then the lower sash can be hingedinwardly and the screw I head l9 now being in the restricted portion ofthe slot 2l will hold the sash against falling to the floor. After theglass in the lower sash has been washed the parting strip 6 is swung tothe position shown in Figure 3 with the upper sash in lowered positionas shown in Figure 7, and at which time brackets 22, carried by theupper sash, are held by headed screws 23 in slots similar to 20 and 2|of the sash lift 2Ia, hence it will be seen that the upper sash can bewashed on both sides without reaching through the window or using aladder.

Referring to Figures 4 and 6, the construction is substantially the sameas in Figures 1 to 3 excepting the inside strip is formed fromtwo hingedsections 24 and 25. The section 25 is slidably engaged with the section24 so it can move vertically for placing the screw heads 26 into and outof registry with the notches 27 in the section 25. It will be noted thatthe section 24 is connectedby a hinged connection 28 similar to theparting strip connection shown in Figure 1.

Referring to Figure 5, showing a further modification, the parting stripis the same as in the other forms, however the inside strip 29 ismounted in a roll M in a similar manner, as shown in Figure 1, butsprings into a channel 30 in the inner side of the lower'sash 4 andagainst the spring action of a channeled spring strip 3|, interposedbetween the sash andthe parting strip. I

The header screws 23 shown in Figure 7are carried by filler blocks 32secured to the frame to the inside of the outside strip 33.

Although the device has been shown, in connection with one side of awindow frame, it is obvious it can be applied to both sides. The sashlift cords and mechanism have been eliminated for purposes of clearness,however it is the intention to use sash cords attached to the lower endsof the sash so that the sash will easily hinge inwardly.

Referring to the modified form shown in Figure 9, the inside strip 24a.and the parting strip 6a. are provided with rolls 34 on their verticaledges, and the strips are longitudinally bowed so they are frictionallyheld when in operative position by the edges of the vertical strips 35,carried by the frame I and by the filler strip 2. The filler strip 2 islongitudinally channeled at 36 to receive the outer r011 34 of theparting strip 6a,, and the frame I is channeled at 37 and 38 to receivethe inner rolls of the partingstrip 6a and the inside strip 24a. It willbe noted that when it is desired to remove the sash the inside strip24a. is pulled inwardlyand hinged to the dotted line positions shown inFigure 9, and after the lower sash 4 is swung inwardly the parting strip6:; is moved inwardly and hinged to the dotted line position where it isspring held as shown in Figure 9 by the entrance of the edges of thestrips 35 into the rolls 34, otherwise the operation is the same. Byslightly bowing the strips 6a as shown in Figure 11 a frictional bindingwill take place on the sash, which will adjust itself to irreg- 4ularities and at the same time act as a spring weather stripping.

Referring to Figure 12 wherein a further modified form is shown, insteadof filler strips, a metallic channeled structure 39 is provided,particularly adapted for metal windows, and the sash 4 and 5' areprovided with spaced flanges 40, which spaced flanges engage the partingstrip 6a in a manner similar to Figure 9, and the inside strip 24aengages the inside flange 40 of the lower sash 4, otherwise thestructure and operation is the same as in Figure 9. It will be seen thatby simply moving the parting strip and inside strip inwardly, andhinging the same inwardly to the dotted line position, the lower andupper sash can be successively removed.

The invention having been set forth what is claimed as new and usefulis:

l. The combination of a sash strip, frame and sash, said sash stripbeing carried by the side of the frame, said strip having one of itslongitudinal edges provided with a roll, a vertical channel in the frameand in which said roll is disposed, said channel being rectangularlyshaped in cross section, a vertical slot in the front wall of thechannel, said strip being slidably mounted in said slot in the frontwall of the channel, said rollengaging opposite walls of the channel,said roll, at its inner side adjacent-the strip, being open, the frontwall of the channel being narrow and-of a width whereby the front wallof the channel willpass through the rollslot when the strip is pulledoutwardly and enter the roll when the strip-is hingedly moved on thefront wall as a fulcrum and forming means whereby the strip can behingedly moved substantially ninety degrees to a parallel positionadjacent the front wall of the channel.

2. A device as set forth in claim 1 wherein the other side of the stripis provided with a roll.

3. A device as set forth in claim 1 wherein the strip is transverselybowed and forming means whereby the strip is transversely flexed againstone side of the channel in the front wall.
